CS0103 The name 'Property' does not exist in the current context #677

Describe the bug

CS0103

After updating CommunityToolkit.MVVM from version 8.0.0 to 8.2.0, I encountered errors in both WPF .Net 7 and WinUI .Net 7 projects. These errors only appear in the Error List in Visual Studio, and I am still able to build the project without any issues. Additionally, I should note that these errors in Visual Studio are intermittent and not consistently reproducible.

Regression

8.0.0

Steps to reproduce

1. Create a WinUI Project (.NET 7)
2. Add CommunityToolkit.MVVM (8.0.0)
3. Add a property with the ObservableProperty attribute
4. Build the project
5. Update CommunityToolkit.MVVM to 8.2.0

Expected behavior

I expect Visual Studio to not show any errors in the Error List after updating the CommunityToolkit.MVVM package, while still being able to build the project successfully.

Duplicate of #493, which is then dependent on https://github.com/dotnet/roslyn/issues/67123. Could you also try using VS 17.6 Preview 5 (or above)? There should be some bug fixes there that might help 🙂
